12 Claims.

The present invention relates to improvements in apparatus for marking, lettering and/or otherwise decorating surfaces of various articles and particularly bottles and the like containers having cylindrical body portions. The invention is particularly concerned with an adaptation of the stenciling method and is similar in many respects to the invention disclosed and claimed in my copending application Serial No. 704,657, flied December 30, 1933, Apparatus for marking or decorating articles.

An object of the present invention is the provision of novel means for supporting and eflecting relative movement between bottles or similar containers and the screen through which coloring material is forced in applying markings or decorations to bottles.

Another object of the invention is to generally improve and simplify the mechanism employed in apparatus of the above character.

Other objects will be in part apparent and in part pointed out hereinafter.

In the drawings: v Fig. 1 is a front elevational view of an apparatus constructed in accordance with my invenopposite side of the view shown in Fig.5. Fig. 7

is a sectional elevational view taken substantially along the line VII--VII of Fig. 6.

Fig. 81s a view illustrating the means for supplying and regulating the supply of air under pressure to the motor employed for reciprocating the screen frame.

In more or less general terms, the apparatus includes a rotary chuck designed to support a bottle or similar container in a cumbent or horizontal position beneath a screen through which the coloring material is forced and applied to the bottle during rotation of the latterand horizontal movement of said screen. The screen and of course its supporting frame, are reciprocated horizontally relative to the bottle or other container by an air operated piston motor. Operation of both the piston motor and bottle holding chuck is controlled by a single manually operated device such for example as av treadle of the type shown.

(Cl. 101-124) v Specifically the present apparatus includes a wheeled base ll carrying a platform II, or table, the latter supporting frames designed to carry the bottle chuck I I and. parts directly associated therewith as will be apparent presently. These frames I! are substantiallyinverted U-shape in side elevation (Fig.1) and includea pair of vertical slideways llat their inner ends, said slideways being spaced apart in thedirection of the length of the platform I I and adapted to accommodate a slide i upon which the bottle chuck i3 is mounted. An adjusting screw it and hand wheel ,ll at the lower end thereof, provide means I whereby the elevationof the chuck may be varied to compensate for variations in the diameter of bottles or other such articles being decorated.

The chuck l3 includesinner and outer sleeves II and I! respectively attached to a holder 20, said inner sleeve being tapered to fit over the neck portion of a bottle andprovided with a vacuum sealing ring II at its outer end adapted for seal- I ing contact'wlth, the shoulder portion of the bottle. These sleeves are threaded intothe holder Ill and as is, undoubtedly apparent, it is intended thatthe airfshall be exhausted from the inner sleeve in order to securely attach the bottle to the chuck. Such exhaustion of air from thesleeve is obtained by way ofan axial opening 22 in a horizontal shaft ltfwhich is journaled in bearings 24 at the upper end of the slide block l5, said :shaft at one end being threaded into the holder 20 and at its'other end carrying a grooved drum 25 or pulley. The passageway 22 in the shaft 23 opens at its inner end into an annular groove 26 provided inla stationary sleeve 21 which surrounds a portion of the shaft between the bearings 24. A supply pipe 2. connects this .annular channel or groove II with a vacuum tank 28' by way of a manually operatedvalve' 38 through which the application ofvacuumfl'to the chuck is, controlled. A treadle ll isoperatively connectedto the-valve ill by means of a rod". A coil spring 33 normally holds, the 'valve 10 in position to break communication between the chuck I 3 and the vacuum tank 20. o

A screen'frame 14' carrying a screen 3 4 is attached to'a' pair of horizontal arms 35' and is disposed immediately above the position occupied bythe bottle B which is to be decorated, said frame in this instance including a pair'of longitudinal sidebars 88 connected by end members 3]. The arms Iiwhich directly support the screen 31 extend from one side of a slide 38 which is mounted for horizontal movement in the direction ofthe length of the platform ,in

horizontal slideways 39, the latter provided at the upper side of the frames i2. Stops near the opposite ends of the sideways limit the extent of reciprocating movement of the slide 38.

For the purpose of forcing the coloring material through the screen 34, there is provided a wiper 4| or squeegee depending from an arm 42, said arm being adjustably mounted upon a horizontal rod 43. This rod 43 is secured at its inner end to a rockable bracket 44 which is pivoted through a hinge pin 45 to the frames I2. Rocking of the bracket 44 for the purpose of reversing the inclined position of the squeegee 4| is obtained by mounting upon the slide 38 a pair of cams 46, said cams bemg spaced apart and positioned for engagement with the horizontal rod 43 at the opposite endsof the path of reciprocation of the slide. These cams 46, as is evident in view of their particular contour, serve to lift the squeegee 4i away from the screen a short distance during the. reversing of the position of the squeegee so that the coloring material may be uniformlgdistributed over the screen. For the purposeof assisting the cams 44 in reversingthe squeegee, a stationary cam 41 is mounted upon the frames l2, said cam being formed with two straight inclined surfaces which engage \the horizontal. rod 43 carrying the squeegee. The rod moves from one inclined surface to the other at each end of the path of reciprocation of the slide 30 and thereby insures reversal of the angular position of the squeegee.

Reciprocation of the screenframe and oscillation of the bottle B about its longitudinal axis are synchronized by providing driving connection between the slide ll and the pulley 25 referred to heretofore as forming a part of the chuck unit. To this end, a cord 45 is wrapped about the pulley 25 and has its opposite ends suitably secured to brackets 49 or arms which are carried by the-slide 35. Thus,it is apparent that reciprocation of the slide 38 operates through the cord 48 to oscillate the pulley 25.. Corresponding oscillatory movement is thereby imparted to the chuck I3 and bottle B supported therein.

Reciprocation of the slide it is obtained by means of a:fl ui d operated piston motor 50 which is mounted upon'the table Ill 'andsecured thereto by means iofholders 5| or: clamps. The piston rod 52 is connected by means of an arm 53 'to the slide 3! under pressure is supplied to the opposite ends of the motor cylinder-54 by way of branchflpipes 55 which are 10f somewhat smaller diameter ;"'than a main supply line 56 through whiehthe'motor is connected to. an air pressure supplf'ta'nk 51. [Air is supplied '.by way of a pipe?" including a check valve 59 and pressure reducing valve 65. A pressure gauge CI is connected-toone of the'branch pipes 55; Normally, constantequal pressure is maintained at both ends of the cylinder 54 owing to the direct connection between said cylinder and the air pres-' sure supply' tank 51. Movementof the piston 62 is obtained by decreasing the, pressure at the opposite ends of the cylinder in alternation. To end, the branch pipes 55 are connected by means of pipes53 to a control valve .54 (Figs.

5 to 8, both inclusive). This valve "64 includes a rotor 55 arranged within a housing 56 and carried by a shaft 51 which at its outer end is attached to pawl and ratchet mechanism 88 serving to hold the shaft and said rotor in any adjusted position. The shaft and the rotor are rotated .in a step-by-step fashion'for a purpose which will be apparent presently, by means including a ratchet 69 pinned to said shaft 6'! and pawl ll engageable with the ratchet and carried by a lever II. This lever H is connected through a rod 12 to the treadle 3| referred to heretofore.

Therotor 55 is provided with four ports II which are equally spaced about the rotor in proximity to its periphery and extend parallel with the axis of the latter. These ports are adapted to be brought into register one at a time with, exhaust ports 14 leading to exhaust pipes 15. These exhaust ports are spaced apart 135 and are disposed directly opposite the point of connection between the housing 56 and the pipes 63. Thus, it will be apparent that register of one of the ports 13 with either of the exhaust ports 14 will result in an immediate drop in the pressure at that end of the cylinder directly communicating with the particular exhaust port 14. Consequently, the piston 62 will move to that end of the cylinder from which the air is being exhausted. Because of the difference in capacity of themain supply pipe 55 and branch pipes ll, opening of either branch pipe 55 to the atmosphere by way of one of the exhaust ports 14 reduces the pressure'in one end of the cylinder below that in the other end. By reference to Fig. 8 this operation is readily understood.

In operation, a bottle is positioned in the chuck i3 as indicated particularly in Figs. 3 and 4. Immediately thereafter, the treadle 3! is depressed with the result that suction or vacuum is applied to the chuck and thereby securely holds the bottle therein. Simultaneously with this operation, the rotor 55 is moved 45 about its axis bringing one of the ports 13 into register with one of the exhaust ports 14. As stated heretofore, this results in movement ofthe piston 52 to one end of the cylinder 54 whereby movement is imparted to the screen 34'. Owing, to the driving connection between screen frame and the pulley 25 through said cord 45, the chuck is oscillated in synchronism with the reciprocating movement of the screen frame. The squeegee or wiper functions as is customary to force the coloring material throughthe screen at the proper points whereby said material is applied to the bottle: Upon completion of one decorating operation another bottle is placed, in the chuck and the operation of the screen, chuck and wiper will be reversed. V
